Hello,

We encounter an issue with M365 apps (Outlook, Work, Excel) on a specific environment ( Remote Desktop Service)

Sometime, when an user open his application (Outlook for instance) on a RDS, an authentification pop and ask for credentials. If the user enter his credentials, he encounter a 1001 error.

« We encountered an issue [1001] »

https://learn-attachment.microsoft.com/api/attachments/5a947921-955a-4688-ad93-acc305bf77c6?platform=QnA

We already try some step to resolve the issue that help in some case but not all the case, and not defintely for a same user ( Issue occur again) :

  • Clear folder C:\Users*yourusername*\AppData\Local\Microsoft\OneAuth and  C:\Users*yourusername*\AppData\Local\Microsoft\IdentityCache
  • Move the user from 1 TSE server to an other TSE)e
  • Clear FSlogix User profil ( The specific one link to FSLogix Office 365 Container technology )

The main issue is that the error can occur again few day laterfor the same user.

We also generate some log from M365 apps client during the signin process with this link to help : https://learn.microsoft.com/en-us/office/troubleshoot/diagnostic-logs/how-to-enable-office-365-proplus-uls-logging

In the log I find the reference to the 1001 error but the log is a bit complex to understand or analyse.

    Currently the user doesn't have to sign into any applications. From time to time they have to authenticate OneDrive. So far 1 user has reported this. But other than that no issues.

    Yes, we are running Microsoft 365 Apps for Enterprise. Currently on 16.0.16924.20150.

    I have RDS 2019 and using FSLogix 2.9.8440.42104

    What appears to be working for me are adding these registry keys

    HKEY_LOCAL_MACHINE\SOFTWARE\FSLogix\Profiles

    "KeepLocalDir"=dword:00000001

    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WorkplaceJoin]

    @=""

    "BlockAADWorkplaceJoin"=dword:00000001

    And updating the Redirections.xml file that is mentioned in HKEY_LOCAL_MACHINE\SOFTWARE\FSLogix\Profiles "RedirXMLSourceFolder"="

    adding the 3 items below.

    <Excludes>

    <Exclude Copy="0">AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy</Exclude>

    <Exclude Copy="0">AppData\Local\Packages\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy</Exclude>

    <Exclude Copy="0">AppData\Local\Microsoft\TokenBroker</Exclude>

    </Excludes>

    What does this change as far as user experience goes? Do they have to sign into all Office Applications every time they connect to RDS? You are running Office 365 Enterprise, I assume?

    Still having the same issue. Some users get the message that license will be disabled after ...date. And as promised after mentioned date they get the 1001error. :-)

    I received my weekly email update from Microsoft again

    Thank you for your time and patience on this case.

    This is a known issue and currently under investigation.

    Refer to the article for reference-

    Thank you for choosing Microsoft Support.

    Quick update from our side...

    We're now only seeing the issue after users change their logon password (Domain/M365 passwords synced via Azure AD Connect). This has been the case since October.

    When a user reports the problem to us now (normally first thing in the morning) we advise them to switch to webmail for the rest of the day and try Outlook again the next morning. In pretty much every case Outlook will be working again.
